Phygelius plant named ‘YAPCOR’

ABSTRACT

A new cultivar of  Phygelius  named ‘YAPCOR’ that is characterized by a compact well-branched habit, burgundy stems and deep coral-pink pendulous flowers. In combination these traits set ‘YAPCOR’ apart from all other existing varieties of  Phygelius  known to the inventor.

Genus: Phygelius.

Species: aequalis×rectus.

Denomination: ‘YAPCOR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofPhygelius, that is grown for its ornamental pendulous red flowers andburgundy stems. The new cultivar is known botanically as Phygeliusaequalis×rectus and will be referred to hereinafter by the cultivar name‘YAPCOR’.

The inventor has been interested for some fifteen years in the genusPhygelius, and has collected many named and unnamed plants of the threespecies of Phygelius, namely Phygelius aequalis, Phygelius capensis, andthe inter-specific Phygelius×rectus (P. aequalis×capensis). The inventorhas recognized that the genus would be more widely produced and soldcommercially if its growth habit would be shorter and more sturdy withnatural self-branching. The species of Phygelius and most of theavailable cultivars, exhibit a vigorous upright growth, such that,although the flowers are much admired, the habit of the plant itself isunappealing to some gardeners. Although it is possible to inducebranching and shorter internodes by the application of plant growthregulators during the production cycle, the effect of such applicationswears off as the season proceeds and the plants fail to remain uprightwithout staking or support from adjacent plants.

‘YAPCOR’ was bred by the inventor in a cultivated area of Cheshire,England. ‘YAPCOR’ is one of three varieties selected for release fromthe same breeding program. The companion varieties ‘YAPOR’ (U.S. Plantpatent application Ser. No. 11/053,242) and ‘YAPYEL’ (U.S. Plant patentapplication Ser. No. 11/053,534) are the subject of contemporaneousapplications. The plant habits of ‘YAPCOR’, ‘YAPOR’ and ‘YAPYEL’ aresimilarly compact, and their flower colors are respectively dark coralpink, orange and yellow. ‘YAPCOR’ arose as follows:

In 1990, the inventor purchased a single plant of Phygelius labeledsimply as Phygelius aequalis, that is, without a cultivar designation.This plant carried the characteristic pale yellow flowers of the speciesPhygelius aequalis but the inventor was attracted by itsuncharacteristic compact habit. The inventor allowed the plant to run toseed, then harvested a quantity of seed which was sown and grown out asa seedling population. The inventor selected a single unnamed plant as auseful parent for a future breeding program aimed at producing a seriesof complementary flower colors on plants with natural compactness andgood branching. The unnamed selection grows to a height of 40 cm in theseason whereas plants of the genus typically achieve heights of orexceeding 70 cm in one growing season. The unnamed selection, which hasnever been made available to the public and is unpatented, has beenmaintained and renewed by vegetative propagation at the inventor'snursery in Somerford, Cheshire, England.

In 1998, the inventor commenced his program to derive a series ofcompact cultivars of Phygelius. The inventor selected a single plant ofPhygelius×rectus ‘African Queen’ (unpatented) for hand cross-pollinationwith the unnamed selection above. The inventor used flowers from bothplants as both pollen donors and pollen receptors and seed was collectedfrom both plants for sowing and seedling grow-out in 1999. From plantsselected in 1999 and vegetatively propagated and grown to flowering in2000, the inventor selected ‘YAPCOR’ as presenting the best combinationof improved plant habit and distinct and clear flower color and overallcompatibility with the contemporaneously selected varieties ‘YAPOR’ and‘YAPYEL’ whose breeding had followed the same procedure, namely the useof a promising parent as alternate parent with the unnamed selection asdescribed in the relative applications ‘YAPOR’ and ‘YAPYEL’).

The distinguishing characteristics of ‘YAPCOR’ are flower color andplant habit. Whereas the one parent, the unnamed selection, exhibitspale yellow flowers without any color variation in the tube, the flowersof ‘YAPCOR’ are dark coral pink with yellow coloration of the inside ofthe corolla tube. Whereas the alternate parent, Phygelius×rectus‘African Queen’ is approximately 70 cm in overall height with sparsebasal branching and salmon-red flowers, ‘YAPCOR’ is approximately 40 cmin height, exhibits multiple branching and dark coral-pink flowers. Theclosest varieties in overall habit known to the inventor are theinventor's varieties ‘YAPOR’ and ‘YAPYEL’ which differ in flowercoloration.

‘YAPCOR’ was first asexually propagated by the inventor in Cheshire,England in 1999 using softwood cuttings. Since that time, under carefulobservation, the distinguishing characteristics have been determinedstable and uniform and reproduces true to type in successive generationsof asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the newPhygelius cultivar ‘YAPCOR’. In combination these traits set ‘YAPCOR’apart from all other existing varieties of Phygelius known to theinventor. ‘YAPCOR’ has not been tested under all possible conditions andphenotypic differences may be observed with variations in environmental,climatic, and cultural conditions, however, without any variance ingenotype.

1. Phygelius ‘YAPCOR’ is 35 cm-40 cm in height and approximately aswide.

2. Phygelius ‘YAPCOR’ branches naturally from the base when grown in acontainer.

3. Phygelius ‘YAPCOR’ may spread by underground stolons when planted inthe ground in conditions where it remains perennial.

4. Phygelius ‘YAPCOR’ exhibits pendulous clusters of dark coral pinkflowers in summer and fall.

5. Phygelius ‘YAPCOR’ exhibits green leaves and burgundy stems.

6. Phygelius ‘YAPCOR’ tolerates temperatures of minus 5° Celsius tominus 8° Celsius.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the distinguishing traitsof the new Phygelius cultivar ‘YAPCOR’. The plant photographed was inits first season of growth at the inventor's nursery in Cheshire,England. The plant was started as a cutting in early spring and pottedinto a 1 liter pot in a cool greenhouse (temperature maintained at orabove 10 degrees Celsius) prior to being stood outside after the risk offrost.

The drawing labeled as FIG. 1 illustrates a plant of ‘YAPCOR’ at thetime of removal from the greenhouse, around May. FIG. 1 depicts thebasal branching habit of ‘YAPCOR’ and illustrates the burgundy flowerstems with flowers still in tight bud.

The drawing labeled as FIG. 2 illustrates a close-up view of aninflorescence of ‘YAPCOR’. FIG. 2 depicts the burgundy stem color, thedeep pink corolla tubes, the exserted stamens and the yellow colorationto the inside of the corolla tube.

All photographs were taken using conventional techniques and areconsidered reasonably representative of the foliage and flower colors of‘YAPCOR’ although to the naked eye flower color appears to varyaccording to ambient light conditions.

BOTANICAL DESCRIPTION OF THE PLANT
